Example
The following example uses myMatrix as a parameter for the MovieClip object's
beginGradientFill() method.
import flash.geom.Matrix;
var myMatrix:Matrix = new Matrix();
trace(myMatrix.toString()); // (a=1, b=0, c=0, d=1, tx=0, ty=0)
myMatrix.createGradientBox(200, 200, 0, 50, 50);
trace(myMatrix.toString()); // (a=0.1220703125, b=0, c=0, d=0.1220703125,
tx=150, ty=150)
var depth:Number = this.getNextHighestDepth();
var mc:MovieClip = this.createEmptyMovieClip("mc_" + depth, depth);
var colors:Array = [0xFF0000, 0x0000FF];
var alphas:Array = [100, 100];
var ratios:Array = [0, 0xFF];
mc.beginGradientFill("linear", colors, alphas, ratios, myMatrix);
mc.lineTo(0, 300);
mc.lineTo(300, 300);
mc.lineTo(300, 0);
mc.lineTo(0, 0);

Example
The following example creates the Matrix object myMatrix and sets its d value.
import flash.geom.Matrix;
var myMatrix:Matrix = new Matrix();
trace(myMatrix.d); // 1
myMatrix.d = 2;
trace(myMatrix.d); // 2
